ADAPTIVE MECHANISMS AND METHODS FOR SUPPLYING VOLATILE DATA COPIES IN MULTIPROCESSOR SYSTEMS - In a computer system with a memory hierarchy, when a high-level cache supplies a data copy to a low-level cache, the shared copy can be either volatile or non-volatile. When the data copy is later replaced from the low-level cache, if the data copy is non-volatile, it needs to be written back to the high-level cache; otherwise it can be simply flushed from the low-level cache. The high-level cache can employ a volatile-prediction mechanism that adaptively determines whether a volatile copy or a non-volatile copy should be supplied when the high-level cache needs to send data to the low-level cache. An exemplary volatile-prediction mechanism suggests use of a non-volatile copy if the cache line has been accessed consecutively by the low-level cache. Further, the low-level cache can employ a volatile-promotion mechanism that adaptively changes a data copy from volatile to non-volatile according to some promotion policy, or changes a data copy from non-volatile to volatile according to some demotion policy.

MEMORY MANAGEMENT - A memory manager that compacts a memory heap and reclaims space allocated to dead entities is disclosed. The memory manager may include threads of a first phase, threads of a second phase, and threads of a third phase. The threads of the first phase may assign a target address to each live entity of the memory heap. The thread of the second phase may update references of the memory heap based upon the target address for each live entity. The threads of the third phase may copy each live entity of the memory heap to its target address.

METHOD OF SEARCHING NEIGHBORING CELL ADDRESS IN SAME RESOLUTION OCTREE STRUCTURE - Disclosed is a method of searing an address in the octree structure having the same resolution. The method of searching address values of the neighboring cells in the octree structure having the same resolution can include performing address encoding of octree cells by giving an inherent address value that is increased according to a depth level of octree to each cell in the octree structure such that address difference values of neighboring cells in the octree structure has a sequential rule; and searching an address value of a neighboring cell that is in contact by a surface with the selected octree cell by using the sequential rule of the address-encoded address difference value of each octree cell. In accordance with an embodiment of the present invention, it is possible to efficiently search address values of neighboring cells that are in contact with an octree cell.

PLUGIN INFRASTRUCTURE FOR HIERARCHICAL TEMPORAL MEMORY (HTM) SYSTEM - A system for implementing a hierarchical temporal memory (HTM) network using a plugin infrastructure. The plugin infrastructure registers the plugins to be used in instantiating the HTM network. The plugin may include one or more functions for creating one or more components of the HTM network in a runtime engine. The plugin is associated with a component specification describing the components of the HTM network created by invoking the functions of the plugin. After the plugin is registered, the plugin infrastructure allows functions of the plugin to be invoked to instantiate The HTM network on a runtime engine. After the HTM network is instantiated, the runtime engine may run the instance of the HTM network to learn and infer the causes of input data. The system may also include one or more external programs to provide various supporting operations associated with the runtime engine by referencing the component specification. The supporting operations that can be performed by the external programs include, among others, validating a netlist defining the structure of the HTM network, build help information for the component, and generating a graphical user interface associated with the HTM network.
